Embodiments of the present invention provide a handover method, system, and device. The method includes: sending, by a source access network device, a handover request or a WLAN offload request to a UE, so that the UE determines information about a target AP according to AP information corresponding to a target RAN and information about a currently accessed AP, and sends a WLAN offload binding request carrying the information about the target AP to a target access network device in the target RAN, so as to complete a RAN handover, where the handover request or the WLAN offload request includes the AP information corresponding to the target RAN, and the AP information corresponding to the target RAN is information about an AP in a WLAN that covers, together with the target RAN, a location of the UE; and receiving, by the source access network device, a handover response or a WLAN offload response returned by the UE. The technical solutions of the present invention can, in a case that a mobile communications network is combined with a WLAN, reduce handover time for a UE to hand over from a source RAN to a target RAN, and reduce an impact on service continuity. |
